%X This paper describes the synthesis,
crystal structure, and photophysical
properties of a new compound Rb2CdBr2I2. It crystallizes in the noncentrosymmetric space group Ama2. In the crystal, all the distorted tetrahedron [CdBr2I2]2– groups are arranged in a way such
that all the Cd–I bonds are located in the same side of the
Cd atoms resulting in a net polarization. Rb2CdBr2I2 showed a powder second harmonic generation (SHG) response
4 times that of KH2PO4 (KDP). The preliminary
measurement indicated that it exhibits a large laser-induced damage
threshold (LDT) of 190 MW/cm2 which is 6 times that of
AgGaS2. It also exhibits a wide transparent region (0.37–14
μm) with a relatively high (up to 490 °C) thermal stability.
All these indicate that Rb2CdBr2I2 is a new promising candidate for NLO materials in the IR region.
